OIL-CAN.

SPECIFICATION forming part of Letters Patent No. 264,841, dated September 19, 1882,

' Application filed July 20, were. (No model.)

To all whom it may concern Beit known that LGHARLES HAMMOND Po- LAND, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Oil-Cans; and I do hereby declare the following to be a full, clear, and exact description of the invenof an oil-can containing myinvention.

tion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompany ing drawings, and to letters or figures of reference marked thereon,which form a part of this specification.

This invention relates to oil cans extensively used in the lubrication of machines in factories and machine-shops; and it consists in certain details of construction, as hereinafter eX- plained.

The drawings accompanying this specification represent, in Figure 1, a vertical section Fig. 2 is a section of a tube or-nozzle heretofore employed, while Fig. 3 shows a solid metal breast embodying my improvements.

In said drawings, A represents the body of 'an oil-can of the form now generally used in factories-that is, a. straight hollow cylinder of tin surmounted by a t'rustro-conical breast, B, and discharge nozzle or tube 0.

It is a frequent practice. among operatives in factories to take out the tube 0 anti in its place insert a bobbin,which has been whittled down at one end forthe purpose, the object in doing this being to permit the oil to escape more readily, as the hole in the bobbin is of larger diameter than that of the tube. To guard as far as possible against thiswaste of oil, I make a division in the breastot' the can, thus forming a large opening, in which it will be difficult to insert a substitute for the tube.

This division may be made in anyi'orm desirable'; but preferably the lower portion,D,of the breastB should have a neck, exteriorly screwthreaded, as shown at b, onto which the upper portion, E, (to which the tube 0 is fastened,)

can be screwed; or the upper portion, with the tube attached, may be exteriorly screw-threaded and screw into a female screwthread in the mouth of the lower portion of the breast B.

"tirely or leaking.

(See Fig. 3.) By this form of construction I obviate the difficulty nowattendiug the con-- strnction of oil-cans, for if the nozzle 0 is knocked out the can is spoiled, and taking off the upper portion of the breast causes such a large opening that it is with difficulty closed. I further propose, as shown in Fig. 3, to make the entire breast of solidmetal instead of being ot' thin material struck up, the lower portion, D, being soldered to the can proper and the upper portion, E, with its nozzle 0, screwing into it, as shown. If the breast is made of solid metal, I still maintain the large-sized opening or aperture G,and,moreover, obviate one great difficulty attending the construction ot'sheet-metal cans now generally in use, in p which itis necessary to securein the thin metal of the breast of a can a screw-bushing to which to attach or screw the nozzle, which bushing, owing to the thinness of the metal, is constantly becoming loosened and coming out en- Moreover, the bore 0 of the tube in my can is. comparatively small and practically of uniform .diameter, as shown.

Heretofore in oil-cans of this class the bore of the tube 0 has been of unequal diameter, as shown in Fig. 2 of the drawingsthat is, its lower part, d, has been greatly enlarged; and another practice of the operatives in mills, in the attempt to make a larger opening for escape of oil, has been to cut off the upper part of the tube 0 and expose the lower and larger part of the tube; or the tube, being of iron or steehis crushed and cracks produceththrough which it will more readily escape. In addition to these disadvantages consequentupon the enlargement of the lower part of the bore of the tube, impurities in the oil are apt to collect at thejunction of the two portions of the bore and obstruct escape of oil. To prevent waste of oil by the first of these two latter practices, I make the bore of the tube small its entire length, so that cutting off the tube at any point shall he of no avail, while to prevent success of the last-named practice I form the tube of brass or other ductile metahwhich, when crushed, shall flatten, but not fracture.

The breast of the can may be a separate breast or its lower portion, D, and the body may be struck up from one homogeneous piece of sheet metal, as shown in Fig. 1 of the drawings, the upper portion, E, being likewise in this instance of sheet metal.

Having thus described the nature and purposes of my invention, I claim, and desire to secure by Letters Patent, the following:

1. The tube 0, of uniform bore, irremovably secured to the separable upper portion, E, of the breast B, and means for attaching and detaching the portion E from the mouth G of the breast proper of the can, substantially as set forth.

2. The tube O,ot ductile metal, having a uni- 15 CHARLES HAMMOND POLAh D.
